Hello, I have had a burning sensation in my eyes that started yesterday and has persisted until now. Just curious as to whether it is simply fatigue or conjunctivitis? No discharge of any kind, however it does feel like something is under my eyelids- gritty feeling- and there is continuous burning. Vision seems normal however the blood vessels are much more apparent now and from slightly further away the sclera looks slightly pinker than usual- not as "red," as i would describe pinkeye. No notable family medical history. Could very well be due to stress and late night studying, however, nothing like this has every occurred before. Hydration is fine as well.
